Feeling alone surrounded by people

I was at my theatre group that i direct surrounded by people and I just felt so alone. No one was sat next to me and I felt like my team were not really there for me. I was trying to direct but spent most of my time having to prompt and I can't watch the actors as well as follow the script. 

I left the rehearsal feeling alone; doubting my ability as a director , knowing that I can't get my team to do what they need to do, hating the script that I have written (it's a panto) oh yes it is !  

Came home and couldn't explain to my husband any of that. Just feel so alone.

Can't talk to the team as I am worried they will walk out on me. Everyone is a volunteer and we do it to raise money for charity.

Already had two people leave and set up their own theatre group because of me. Now frightened it will happen again so I don't tell them how I feel so then I feel even more alone.
